## UNIT: Complete Milestone {{milestoneId}} ("{{milestoneTitle}}")

{{include:working-directory}}

## Your Role in the Pipeline

All slices are done. You are closing out the milestone — verifying that the assembled work actually delivers the promised outcome, writing the milestone summary, and updating project state. The milestone summary is the final record. After you finish, the system merges the worktree back to the integration branch. If there are queued milestones, the next one starts its own research → plan → execute cycle from a clean slate — the milestone summary is how it learns what was already built.

All relevant context has been preloaded below — the roadmap, all slice summaries, requirements, decisions, and project context are inlined. Start working immediately without re-reading these files.

{{inlinedContext}}

Then:
1. Use the **Milestone Summary** output template from the inlined context above
2. Inspect the inlined or linked **MILESTONE VALIDATION** verdict. If the verdict is not `pass` (including `needs-attention` or `needs-remediation`), record it as a **verification failure** and follow the failure path. Do NOT call `complete_milestone` for a non-pass validation verdict.
3. {{skillActivation}}
4. **Verify implementation evidence exists.** Use the inlined validation verdict and slice summaries as the primary proof that implementation happened. If a slice summary lists non-`.sf/` key files, accepted verification commands, or committed work, that satisfies code-change verification for already-integrated milestone work. Run only `git status --short` to check for unresolved local changes. Do **not** inspect git history, compute merge bases, or run branch-diff archaeology unless the validation verdict and slice summaries are missing or contradictory. If no slice summary or validation evidence names implementation files, record this as a **verification failure**.
5. Verify each **success criterion** from the milestone definition in `{{roadmapPath}}`. For each criterion, confirm it was met with specific evidence from slice summaries, test results, or observable behavior. Record any criterion that was NOT met as a **verification failure**.
6. Verify the milestone's **definition of done** — all slices are `[x]`, all slice summaries exist, and any cross-slice integration points work correctly. Record any unmet items as a **verification failure**.
7. If the roadmap includes a **Horizontal Checklist**, verify each item was addressed during the milestone. Note unchecked items in the milestone summary.
8. Fill the **Decision Re-evaluation** table in the milestone summary. For each key decision already inlined in the context above (from the DB decisions table) that was made during this milestone, evaluate whether it is still valid given what was actually built. Flag decisions that should be revisited next milestone.
9. Validate **requirement status transitions**. For each requirement that changed status during this milestone, confirm the transition is supported by evidence. Requirements can move between Active, Validated, Deferred, Blocked, or Out of Scope — but only with proof.

### Parallel Follow-up Classification

Before completion, classify leftover work into one of two buckets:
- **Blocking completeness work** — required to truthfully claim the milestone is done. Missing contract tests, unresolved bugs, missing proof for promised behavior, required launch/safety checks, or anything needed for the milestone's stated outcome. These BLOCK completion.
- **Parallel hardening / follow-up work** — useful but not required for the milestone's honest claim. Examples: broader regression coverage, extra negative tests, load/perf expansion, docs improvements, cleanup, deeper observability, additional adapters.

If work falls into the second bucket, do not fail the milestone just because it exists. Record it as a follow-up for a parallel track or later milestone. If it falls into the first bucket, the milestone is not complete.

**DB access safety:** Do NOT query `.sf/sf.db` directly via `sqlite3` or `node -e require('better-sqlite3')` — the engine owns the WAL connection. Use `milestone_status` to read milestone and slice state. All data you need is already inlined in the context above or accessible via the `sf_*` tools — never via direct SQL.

### Verification Gate — STOP if verification failed

**If ANY verification failure was recorded in steps 2, 4, 5, or 6, you MUST follow the failure path below. Do NOT proceed to step 11.**

**Failure path** (verification failed):
- Do NOT call `complete_milestone` — the milestone must not be marked as complete.
- Do NOT update `.sf/PROJECT.md` to reflect completion.
- Do NOT call `update_requirement` to mark requirements as validated.
- A non-pass validation verdict is a verification failure, even if it is terminal for validation-loop purposes.
- Write a clear summary of what failed and why to help the next attempt.
- Say: "Milestone {{milestoneId}} verification FAILED — not complete." and stop.

**Success path** (all verifications passed — continue with steps 10–14):

10. For each requirement whose status changed in step 9, call `update_requirement` with the requirement ID and updated `status` and `validation` fields. Do this BEFORE completing the milestone so requirement updates are persisted.
11. **Persist completion through `complete_milestone`.** Call it with the parameters below as soon as steps 2, 4, 5, 6, and 10 are satisfied. Do not keep reading historical commits or re-running broad test suites after the requirements are updated. The tool updates the milestone status in the DB, renders `{{milestoneSummaryPath}}`, and validates all slices are complete before proceeding.

   **Required parameters:**
   - `milestoneId` (string) — Milestone ID (e.g. M001)
   - `title` (string) — Milestone title
   - `oneLiner` (string) — One-sentence summary of what the milestone achieved
   - `narrative` (string) — Detailed narrative of what happened during the milestone
   - `successCriteriaResults` (string) — Markdown detailing how each success criterion was met or not met
   - `definitionOfDoneResults` (string) — Markdown detailing how each definition-of-done item was met
   - `requirementOutcomes` (string) — Markdown detailing requirement status transitions with evidence
   - `keyDecisions` (array of strings) — Key architectural/pattern decisions made during the milestone
   - `keyFiles` (array of strings) — Key files created or modified during the milestone
   - `lessonsLearned` (array of strings) — Lessons learned during the milestone
   - `verificationPassed` (boolean) — Must be `true` — confirms that code change verification, success criteria, and definition of done checks all passed before completion

   **Optional parameters:**
   - `followUps` (string) — Follow-up items for future milestones
   - `deviations` (string) — Deviations from the original plan
12. Update `.sf/PROJECT.md`: use the `write` tool with `path: ".sf/PROJECT.md"` and `content` containing the full updated document reflecting milestone completion and current project state. Do NOT use the `edit` tool for this — PROJECT.md is a full-document refresh.
13. Review all slice summaries for cross-cutting lessons, patterns, or gotchas that emerged during this milestone. Call `save_knowledge` for any non-obvious, reusable insights.
13b. Review the global `~/.sf/agent/upstream-feedback.jsonl`. For any sf-internal anomaly that recurred across multiple slices in this milestone but is not yet captured, file it now via `report_issue`. The milestone-close agent is the last line of defense for systemic sf bugs that single-task agents missed.
14. Do not commit manually — the system auto-commits your changes after this unit completes.
- Say: "Milestone {{milestoneId}} complete."

**Important:** Do NOT skip validation verdict, code change, success criteria, or definition-of-done verification (steps 2 and 4-6). The milestone summary must reflect actual verified outcomes, not assumed success. Verification failures BLOCK completion — there is no override. The milestone stays in its current state until issues are resolved and verification is re-run. **If a verification tool itself fails, errors, or returns unexpected output, treat it as a verification failure** — never rationalize past a tool error ("tool didn't respond, assuming success" is forbidden). A tool that cannot verify is a tool that did not verify.

**File system safety:** When scanning milestone directories for evidence, use `ls` or `find` to list directory contents first — never pass a directory path (e.g. `tasks/`, `slices/`) directly to the `read` tool. The `read` tool only accepts file paths, not directories.
